Brown rot is a fungal disease of stone fruits, such as nectarine, peach, apricot, cherry, plum, prune, and almond trees.
Brown rot identification
Brown rot appears as brown, withered blossoms (blossom blight), cankers, and rotten fruit. Infected twigs may also display brown, sunken areas that ooze a sticky brown goo that contains millions of fungal spores of Monilinia fructicola. Fruit mummies hold even more potential infestations.
Brown rot control
Copper fungicides can minimize fungal populations, as can removing mummies and pruning out diseased tissue.
How to prevent brown rot
Pruning for better airflow can reduce the likelihood of infection, as can furrow irrigation. Do not allow sprinklers to wet blossoms.
